【摘要】 随着大、中型水、火电机组在励磁方式上由传统的旋转交流励磁机方式向静止自励励磁方式转变,对励磁变压器技术也提出了较高要求。三峡水电厂励磁变压器是应用H级绝缘杜邦Reliatran技术开发的,分析了主要技术参数的计算及结构的确定方法,介绍了该变压器的相关试验方法。更多还原

【Abstract】 Along with the excitation mode transformation from the traditional,rotating AC exciter to static self-excitation mode for large or medium hydropower and thermal power generation unit,the higher requirement was put forward for excitation transformer technique.The excitation transformer of Three Gorges Hydropower Plant was developed by using of H class insulating and Du Pont Corporation Reliatran technique.The calculation of main technical parameters and determination of structure were analyzed,and related test method of the transformer was introduced.更多还原
